Are similar acoustic soundscapes perceived as similar?: Paper SS29-355.
2006 (English)In: EuroNoise 2006: Advanced Solutions for Noise Control., 2006Conference paper (Other academic)
Health guidelines are concerned with soundscapes as coherent wholes (emissions from all sounds) and everyday life also takes place in soundscapes. Current noise control focuses on sound level change for singular sources, isolated from invariant background and other component sounds. By applying a dualistic similarity approach to data sets of perceptual soundscapes and acoustic soundscapes, it was possible to meaningfully differentiate properties of acoustic soundscapes of relevance for improving urban and suburban soundscapes. Apart from the mere presence of common sounds (e.g., birds, sounds of nature or technological sounds), meaningful differentiations of soundscapes include: (1) the relative proportion of direct and shielded sounds in background soundscapes, (2) the modification of loudness/softness and eventfulness/uneventfulness by acoustic quality, and (3) the “sound signatures” traceable to the relative foreground-background character of perceived soundscapes. Acoustically similar soundscapes (evolutionary spectra) were not always perceived similar, because the reasons for the two types of similarities differ. This fact calls for new ways to assess the acoustic soundscapes such that adequate design tools for coherent soundscapes can be developed.
